APPARATUS FOR C OMPRESSING GASES.

. SPECIFICATION forming part of Letters Patent No. 686,427, dated November 12, 1901.

tnfinttrta Jnly 2a, 1961.

To all whom it may concern:

Be it known that LWILLIAM THOMAS Sues, a subject of the King of Great Britain, and a resident at'Vincent Works, Regency street, Westminster, London, England, have invented new and useful Improvements in Apparatus for Compressing Gases, of which the following is a specification.

The chief object of this invention is to provide a simple and convenient apparatus for pumping gas used under pressure in incandescent-gas lighting; but the apparatus may also be employed for pumping gaseous fluids for any other purpose.

The apparatusis preferably to be driven by steam, and in places where ordinary steam is not available, as in private houses and so on, it will include a steam-boiler to be heated by gas; but obviously any othermotor fluid may 7 be employed, if desired.

In the accompanying drawings, Figure 1 is a plan view of an apparatus constructed according to my invention with two steam-motor cylinders and two compressing cylinders. Fig. 2 is an elevation, partly in section, taken approximately on the line X X, Fig. 1; Fig. 3, an underside view of one of the motorcylinders; Fig. 4, a plan view of the'steam ports and passages provided in the base-plate of the apparatus for the said cylinder; Fig. 5, an under side View of one of the compressing-cylinders 5 Fig. 6, a plan View of the ports and passages provided in the base-plate for the latter cylinder; Fig. 7, a horizontal section in the line Z Z of Fig. 2

A is a cast-metal baseplate containing steam and exhaust passages on b and inlet and outlet gas-passages c d, as indicated by dotted lines and which'will be more particularly referred to hereinafter. The base-plate has hollow bosses B and O to receive steam and compressing cylinders and -alsoa stepbearing D for a vertical crank-shaft.

E F are steam or other motor-fluid cylinders arranged radially and seated on the base A, and G H are gas compressing cylinders similarly seated and arranged.

It will be understood that I may use three or any other number of motor-cylinders and compressor-cylinders; but in any case I employ the same number of motor-cylinders as Serial No. 69,383. (No model.)

of compressor-cylinders, so as to maintain a balance of parts.

The steam and gas cylinders are each provided with a boss B or O on its under side, which fits into one or other of the hollow bosses B or C, in which the cylinders oscillate horizontally. In these cylinder-bosses are the ports and passages to opposite ends of the cylinders, as shown in Figs. 3 and 5. These ports are alternately inlet and exhaust ports as the cylinder oscillates.

Fig. 4 represents one of the hollow bosses B, in which there are four ports, two being steam-ports a and two exhaust-ports b. The cylindersE and F are kept down on their seats by springs I, having a bearing on the under side of a bracket 1*, bolted to the base A or in any other convenient manner.

Fig. 5 shows the face of the boss C of a gascylinder G or H, as before referred to.

Fig. 6 is a plan view of the corresponding hollow boss 0 of the base-plate.

The cylinders G H will be held down in practically the same manner as indicated for the steam 7 cylinders. These cylinders are of larger dimensions than the steam-cylinders and are provided with double the number of ports and passages as shown for obvious reasons. The oscillation of these cylinders is effected by means of the cranked shaft J, with which the piston-rods of all the cylinders are connected in any convenient manner and i with any convenient means for cutting off the supply of steam to work the apparatus as the pressure of the gas increases, so that the movement of the compressors will be reduced or practically stopped, or when the apparatus includes a boiler the supply of heating-gas to the boiler may be gradually shut oft, so that less steam will be generated. If necessary,

lation to which the said motor-cylinders and compressing-cylinders are radially arranged, and connections between the said crank-shaft and the piston-rods of said motor-cylinders and compressing-cylinders, substantially as herein described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

WILLIAM THOMAS SUGG.
